ATX12VO (12V Only) Desktop Power Supply
Design Guide
Other Low Power System Requirements (Required)
To help meet multiple world-wide Energy Regulations the +5VSB standby rail must meet the following efficiency as shown in Table 4-5 which is measured with the main outputs off (PS_ON# high state). These World-Wide Energy Regulations and standards include: Blue Angel* system requirements, RAL-UZ 78, US Presidential executive order 13221, ENERGY STAR*, ErP Lot 6 requirements (2010 and 2013 levels), and 2014 ErP Lot 3 requirements. Additionally, if any Computers use an Alternative Low Power Mode (ALPM) then the +5VSB standby efficiency has similar requirements as shown below.
